1 Claim.

This invention is directed to an improvement in storm windows or doors of the convertible type, providing for the usev of glass panels in winter and screen panels in summer.

An important and necessary characteristic of windows or doors of this type is to provide for a comparatively perfect sealing fit of the removable sections together with securing means therefor which will permit easy and convenient manipulation of the sections as may be desired or necessary.

The primary object of the invention is,'there fore,y the provision ofrmeans kwhereby the sash "of either forrn'may be readily placed in or removed from the frame, with the cooperation of the sash and frame and the securing means contributing to provide a substantial sealing relation of the parts.

A further object of the invention is the relative formation of certain meeting parts of the sash and frame as to provide a more or less wedging intert for more effective sealing, and

to particularly utilize this formation of the lower sash in conjunction with the connecting means therefor to permit a limited opening of the lower sash when desired without removing it from the frame.

The invention is illustrated in the accompanying drawings, in which:

Figure 1 is a view of the improved storm accessory, shown as a Window.

Figure 2 is a side elevation of the same.

Figure 3 is a broken detail in perspective showing the mounting for the sashes.

Figure 4 is a perspective view of the upper and lower sashes.

Figure 5 is a detail view showing part of the frame to bring out the details of construction.

The improved structure, which is shown and will be particularly described as a storm window, includes a more or less conventional main frame I, of a length and width desired in the particular use. This frame I includes side bars 2, a top bar 3, and a bottom bar 4. The top bar 3 is of increased vertical dimensions for a, particular.

compensating function to be later referred to, and the top bar 3 and side bars 2 are formed with a bead strip 5 flush with the outer surface of the frame and providing a sealing limit for the sash. The lower surface of the top rail 3 is formed with a channel or recess 6, of which the bead strip forms the outer wall.

The bead strips 5 on the side bars 2 of the frame are each formed, at points slightly above the position of the bottom of the lower rail of opening toward the rear of the frame and of less depth than the corresponding dimension ofthe bead strip. These depressions receive holding lugs on the upper sash as will later appear. Sliding-latch keepers 8 are also secured to the inner surfaces of the side bars 2, just opposite the depressions 1.

The upper surface of the bottom bar 4 is rather sharply inclined,` as at 9, downwardly toward the front of the frame to provide a sealing and holding surface, and each side rail, immediately above the surface 9, is formedfrwith a downwardly and outwardly inclined positioning and holding groove IIJ. These grooves II) are of relatively shallow depth, open at their upper ends at II through the rear surfaces of the sidev bars and terminate slightly above the inclined surface 9.

The upper sash I2 includes forming rails shaped on their inner edges to receive a window pane or screen cloth according to their contemplated use. The upper rail I3 is formed with an upstanding strip I4 designed when the sash is applied to fit more or less snugly in the channel 5 of the top bar 3 of the main frame I. The side rails I5 of the upper sash I2 are provided with holding lugs I5 to accurately seat in the depressions 'I in the bead strips 5 of the side bars 2 to thus support the upper sash when applied, and sliding latches I'I or other appropriate fastenings are provided on the inner surface of the upper sash in positions to cooperate with the keepers 8, to removably secure the upper sash in place.

The lower sash I8 is also of rail construction to accommodate a, window pane or screen, the lower surface I 9 of the lower rail 2U being formed as a complementary fit on the inclined surface 9 of the bottom bar 4 of the main frame. The side rails 2I of the lower sash are provided with outstanding pins 22, designed for sliding fit in the holding grooves I0, and positioned to bear against the ends of the grooves when the inclined surfaces 9 and I9 are in contact.

The upper edge surface of the lower sash and the lower edge surface of the upper sash are similarly inclined at 23 outwardly and downwardly of the main frame to insure substantial sealing interiit when the sash are in position. The lower sash carries a snap latch 24 of any conventional form to cooperate with a keeper 25 on the upper sash to removably lock the sash in applied positions.

The sash are applied in an obvious manner, the

lower sash being capable by reason of its pivotal support and inclined lower edge of being tilted inwardly to a limited degree and held partially open when desired. Both sash are more or less eiectively sealed when in position and are locked against opening from the outer side of the frame.

The increased height of the top bar 3 of the frame is to compensate for the height of the lower rail of the lower sash of the regular win dow, in order to permit the lower Isash I8 of the improved storm window to operate freely when bottom sash of regular window is raised. This same result can be provided for by increasing the vertical dimension of the top sashof the storm window a corresponding amount, contemplated if desired. v

The improvement readily lends itself to a metal frameV and sash instead of `the wooden structure illustrated, and of course the dimensions -of the respective parts may be determined by therequired .size of theparticular window desired.

lThe Ydetails/of structure, particularly in 'the cornert'ible Yfeatures lmay with equal 'advantage be applied to door construction, 'if desired.

' What is claimed as new is:

-A storm .sash including a frame .having side bars, ra topi-bar and a bottom bar, sash limiting beads projecting inwardly from the Vsash receiving surfaces of the side bars with the/.outer surlfaces of the beads flush with the 'outer surfaces r .of-theside bars, the upper surface of the vbottom bar being inclined upwardly from Vthe beads, a lower V:sash iitting between the side bars to bear relative to the frame, the pivot pins and bottoms of the grooves being spaced when the sash is in f operative closed position in the frame, whereby Y lthesash may be tilted on the inner margins of the inclined surfaces of the sash and frame until the VApivot pins contact the bottoms of the grooves to thereby prevent further swinging movement of the sash and 'holdsuch sash in open position while still connected to the frame.
